idk bout the ban but try this in console cg_fov 100
if it tells you something like its readonly or other shit
you cant activate it without making a mod or maybe using a hack for it idk if a hack for that exists but there is a risk you get a ban so do it with a mod check the tutorial section some guy is asking for sv_cheats activation follow my tutorial there and just change ( ''sv_cheats'', 1 ) to ( ''cg_fov'',100 ) or just follow the sv_cheats activation and enter sv_cheats 1 in console hope i helped
